Abstract

Dans un système de traitement de données à l'aide d'objets portatifs (I) tels que des cartes à mémoire (11, 12, 13, 14, 15) et à circuits de traitement (10), dont une première zone de mémoire (II) est effaçable et inscriptible électriquement sur requête des circuits de traitement de l'objet, des nombres aléatoires sont générés en prenant en compte un premier paramètre prélevé dans la première zone (11) et au moins un second paramètre inscrit dans une seconde zone (12) non volatile de l'objet, le contenu de cette seconde zone étant modifié à chaque effacement de la première, de sorte que la combinaison des paramètres ne se retrouve jamais à l'identique suite aux divers effacements de la première zone.
